Supernovae in Early-Type Galaxies: Directly Connecting Age and Metallicity with Type Ia Luminosity

open access: yes, 2008
We have obtained optical spectra of 29 early-type (E/S0) galaxies that hosted type Ia supernovae (SNe Ia). We have measured absorption-line strengths and compared them to a grid of models to extract the relations between the supernova properties and the ...

Abundance diagnosis of E+A (post-starburst) galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2007
E+A galaxies are characterized as a galaxy with strong Balmer absorption lines but without any [OII] or H$ $ emission lines. The existence of strong Balmer absorption lines means that E+A galaxies have experienced a starburst within the last $

Microfluidic Engineering of Chitosan‐Coated Nanoemulsions for Controlled Release and Stability in Space Pharmaceutics

open access: yesAdvanced Materials Technologies, EarlyView.
Microfluidic engineering enables the fabrication of chitosan‐coated, melatonin‐loaded nanoemulsions with controlled release and enhanced physicochemical stability for space pharmaceutics. Interfacial biopolymer coating modulates droplet behavior under accelerated thermal stress and simulated microgravity.

Comparing Star Formation Histories and Evolutionary Pathways of Post-starburst and E+A Galaxies in TNG50 and SDSS-IV MaNGA

open access: yesThe Astrophysical Journal
E+A galaxies represent a class of recently quenched objects, with spectra that show evidence of a previous substantial starburst and strong Balmer absorption lines indicative of A-type stellar populations.

The spatial distribution of galaxies of different spectral types in the massive intermediate-redshift cluster MACSJ0717.5+3745 [PDF]

open access: yes, 2008
We present the results of a wide-field spectroscopic analysis of the galaxy population of the massive cluster MACSJ0717.5+3745 and the surrounding filamentary structure (z=0.55), as part of our systematic study of the 12 most distant clusters in the MACS

Multi‐Dielectric Metasurfaces for Ultrabright, Tunable Structural Color and Reconfigurable Optical Filtering with Extraordinarily Large Color Span

open access: yesAdvanced Optical Materials, EarlyView.
Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.

Equilibrium Figures inside the Dark-Matter Ring and the Shapes of Elliptical Galaxies

open access: yesOpen Astronomy, 2015
We solve the general problem of the theory of equilibrium figures and analyze two classes of liquid rotating gravitating figures residing inside a gravitating ring or torus.

Dusty-wind-clear JWST Super-early Galaxies

open access: yesThe Astrophysical Journal Letters, 2023
The JWST discovery of a number of super-early (redshift z > 10) blue galaxies requires these systems to be essentially dust free in spite of their large stellar masses. A possible explanation is that dust is evacuated by radiatively driven outflows.

The Luminosity Function of Early-Type Galaxies at z~0.75

open access: yes, 2004
We measure the luminosity function of morphologically selected E/S0 galaxies from $z=0.5$ to $z=1.0$ using deep high resolution Advanced Camera for Surveys imaging data. Our analysis covers an area of $48\Box\arcmin$ (8$\times$ the area of the HDF-N) and
